Hi all,
I am a new user of JBoost and I'm very enthusiastic and happy to use it.
It's really simple to start and I succeed easily in having some good
results.
I would ask you a little question.
When I run my Jboost command with generation of python code, I have this
exception :
Exception occured while attempting to write Python code
Message:java.lang.RuntimeException: Type of split not allowed
java.lang.RuntimeException: Type of split not allowed

Have you an idea ? I look the code but I did not succeed to fix the problem.
I have different types of value in my spec file : number, text, and finite
(none,same,not)
Thanks in advance,
Regards,
Julien Henot

Hi Julien,
First, thanks for the detailed error message.
While I'm no longer a main developer (and so I won't edit the public
repository), it looks like the problem is a simple typo.
In AlternatingTree.java, there should be code that looks like this (line
numbers may not match up):
1051 private String makePythonCode(SplitterNode sn, String tab) {
1052 String code = "";
1053
1054 Summary summary=sn.splitter.getSummary();
1055
1056 code += tab + (allDefined
1057 ? " "
1058 : "if def(" + (summary.index+1) + "):")
1059 + " # " + sn.id + "\n";
1060 String stab = (allDefined ? tab : tab);
1061 switch(summary.type) {
1062 case Summary.EQUALITY:
1063 code += stab + "if self.get_data_value(x,'" + ad[(summary.index)].getAttributeName() + "') == " +
1064 ((Integer)summary.val) + ":\n";
1065 code += makeMatlabCode(sn.predictorNodes[0], stab + "\t");
1066 code += stab + "else:\n";
1067 code += makeMatlabCode(sn.predictorNodes[1], stab + "\t");
1068 break;
1069 case Summary.LESS_THAN:
1070 code += stab + "if self.get_data_value(x,'" + ad[(summary.index)].getAttributeName() + "') <= " +
1071 ((Double) summary.val) + ":\n";
1072 code += makePythonCode(sn.predictorNodes[0], stab + "\t");
1073 code += stab + "else:\n";
1074 code += makePythonCode(sn.predictorNodes[1], stab + "\t");
1075 break;
1076 default:
1077 throw new RuntimeException("Type of split not allowed");
1078 }
1079
1080 return code;
1081 }
Notice the three lines:
1065 code += makeMatlabCode(sn.predictorNodes[0], stab + "\t");
1066 code += stab + "else:\n";
1067 code += makeMatlabCode(sn.predictorNodes[1], stab + "\t");
These calls should be changed to recursively call the Python method
whereas they are currently calling the matlab method:
1065 code += makePythonCode(sn.predictorNodes[0], stab + "\t");
1066 code += stab + "else:\n";
1067 code += makePythonCode(sn.predictorNodes[1], stab + "\t");
You may also have to change the line
1064 ((Integer)summary.val) + ":\n";
So that it can handle strings (though the strings may be converted to
integers, and this may be easier to edit once the python code has been
outputted using a dictionary, etc). I don't remember the exact internal
string representation, but you can email again if you have further
problems.
Running 'ant jar' or 'ant dist' in the top directory will compile the code
(make sure the file 'JBOOST_DIR/dist/jboost.jar' has been updated).

Hi aaron,
Thanks for your answer !
I have changed the code of makePythonCode as you recommend, but I still have
an error:

I tried different casting, but I have still an error.
Thanks in advance.

Great to hear that your able to edit and compile the code!
Can you send me the *output.tree file from the run? I'm interested to see
what kind of splitters the algorithm is using for your data.
The types of splitter are given in src/jboost/learners/Summary.java
public static final char EQUALITY = 1;
public static final char LESS_THAN = 2;
public static final char CONTAINS_ABSTAIN = 3;
public static final char CONTAINS_NOABSTAIN = 4;
makePythonCode currently only works with EQUALITY and LESS_THAN. I'm not
actually familiar with the other two splitters.
Another easy way to check what splitters are being used is to output the
following prior to the case statement:
System.out.println("Splitter summary: " + summary.type)
We should be able to get an exact diagnosis this way.
Assuming this is the problem, it looks like there is some example code for
how to handle CONTAINS_ABSTAIN and CONTAINS_NOABSTAIN at lines 859-885 in
String makeCode(SplitterNode sn, String tab).

Hi Aaron,
Thanks for your answer.
Instead of this line code
throw new RuntimeException("Type of split not allowed");
I write this following code to know which kind of summary type causes this
issue :
if (summary.type == Summary.CONTAINS_ABSTAIN){
throw new RuntimeException("Contains abstain not allowed");
} else if (summary.type == Summary.CONTAINS_NOABSTAIN) {
throw new RuntimeException("Contains noabstain not allowed");
} else {
throw new RuntimeException("Type of split not allowed");
}
This is the stracktrace :
Message:java.lang.RuntimeException: Contains noabstain not allowed
So you are right. This is a issue of not handled splitters for python
generation code.
Do you know if this kind of splitters comes from finite attribute type?
Because the problem appears when I put in my attribute some finite and text
types.
I will look the code of MakeCode method to know how to handle this splitter
for python.
Thanks.
Regards,
Julien Henot.
